If we see a bogus $PIR table entry, just ignore it. The MPIIX has
...
entries for the IRQs used by the IDE controller, which aren't really
PCI IRQs (they're ISA compat IRQs), and thus have link values that
don't make a lot of sense.

PCI interrupt routing fixup code, from UCHIYAMA Yasushi's PCI BIOS
...
patches, cleaned up and heavily reworked by me. Basic algorithm is
the same, although the code structure is now quite different.
Main differences:
- Initialization path is totally different.
- We use the `compat router' information, if present, to determine which
PCI ICU driver we should use.
- Fixup configuration headers on devices not on bus 0.

Basic interface to the PCI BIOS and PCI Interrupt Routing table, separated
...
out from UCHIYAMA Yasushi's PCI BIOS patches, and fairly heavily reworked
by me.
Main differences:
- Only use the PCI BIOS to get the config mechanism and interrupt routing
info for now. No need to use the BIOS for PCI config access right now,
since the old mechanism works fine, and this keeps the code smaller.
- PCI BIOS initialization code path is much different.
- Always use the $PIR table if it exists, and only fallback to the
PCI BIOS 2.1 GetInterruptRouting call if it's not there.
This module does not include any of the fixup code; that is coming
in separate commits.

Match PCI-ISA bridges on class/subclass instead of vendor/device.
...
2 reasons:
-no need to keep a list of all known parts
-there is at least 1 bridge (ACC micro 2051) which reports the same
device ID for its various subfunctions; this would require an additional
check in the match function
(keep the old list inside #if 0 in case one of the historical bridges
doesn't report the right class/subclass - I can't check them all)
